- the information signal AF_info represents the ORing of the driving signals af and afl. If one of the driving signals af or afl shows a logic 1, then the elevator car 14 is in motion and the information signal AF_info is 1. If none of the driving signals af or afl is 1 If the driving signals af and afl are so-called driving direction signals and af indicates, for example, the upward travel and afl the downward travel (bottom line in the above Table), then a special case can occur. If both of the travel direction signals af or afl are logically one, then an error has occurred because obviously the elevator car can not travel in both directions at the same time. This error is marked with 1 * in the table.
- the driving signals or direction signals af and afl may be DC or AC signals, which may preferably be between 24 V DC and 230 V AC.
- the brake monitor 100 is advantageously designed accordingly.
- the elevator installation 10 is stopped.
- the design is selected so that the elevator installation 10 completes a journey before it is blocked.
- fault memory or error counter are used as part of the brake monitor 100.

Under certain circumstances, it is accepted that a path is driven with the (holding) brake applied. Such a ride with the (holding) brake on is unproblematic since the wear is not very great.
- Table 2 shows the various signals and a design of the error memory and / or error counter of a preferred embodiment.
- the relays RE1 / RE2 open 2 s after af changes from 1 to 0 if the counter is Cl> 2 or if the counter C3 is> 4 after 5 min.

- the Laufzeitbegrenzer Tl a maximum delay is set in the event of a fault. When this maximum transit time is exceeded, the elevator system is shut down.
- timer timer
- clock When Laufzeitbesky preferably timer (timer) or clock are used.
- a corresponding command / rule set defines the individual steps and the parameters (such as the number of allowed errors, the length of the time window tA (eg 3 s), the maximum time (eg 60 s) that the delay limiter Tl uses, etc .) are given.
- the microprocessor 102 can execute the command / rule set and react in the desired form depending on the situation.

- the method according to the invention for monitoring a brake system 13 is characterized by the following steps, which are shown in a schematic flow diagram in FIG. 7.
- a first brake release signal kb of the brake system 13 and a first drive signal af of the drive controller 12 are received (steps S2 and S4). It is then monitored whether a first brake release signal kb follows after application of the first drive signal af (i.e., the drive signal af goes from 0 to 1, step S2) (step S4).
- a brake release signal kb occurs when a brake of the brake system 13 has been released.
- step S3 If now this brake release signal kb does not occur within a time window tA (step S3), then the relay circuit 103 is activated (step Sil) to interrupt the safety circuit 20 of the elevator installation 10 or a control voltage of the drive control 12. As a result, the elevator installation 10 is shut down.
- This error counter Cl starts with a zero and increases in steps of one (+1). Now, if the running signal af goes from 1 to 0 (ie, if the elevator car stops, step S7), it is checked if more than two errors have been stored in the error counter C1 (step S8). If more than 2 errors have actually occurred, the elevator installation 10 is shut down (step Sil). However, if fewer than two errors have occurred, the method branches back to a point prior to step S2.
- a permanent error can be stored in the continuous error memory E in order to prevent the elevator installation from being started up again by simply switching it on and off.
- the method of FIG. 7 branches immediately from step S1 to the end (step S1).
- the flowchart shown in FIG. 8 represents a preferred implementation of the invention.
- the error signal A (see Table 2) can optionally be evaluated and processed.
- a further delay limiter T5 (not shown)

- the elevator equipment 10 may be stopped (step S29).
- the brake system 13 may have two brake arms that open independently of each other (ie, release a brake shoe of the brake) and close. In braking systems 13 with independent brake arms, a brake magnet, a spring and a monitoring switch are present per brake arm. Other brake systems 13 have two brake arms, but they are interdependent. In this case, a brake magnet, a spring and a monitoring switch are used.
- Each brake arm is preferably associated with a brake contact K1 or K2.
- a first electrical brake contact Kl of the brake system 13 with the first brake contact switch of the brake system 13 and a second electrical brake contact K2 of the brake system 13 with the second brake contact switch of the brake system 13 are electrically connected.
- Each of the brake contact switches outputs a brake release signal (kb or kbl) when the first, respectively the second brake arm of the brake system 13 opens or releases.
- a separate brake monitor 100 is installed in the existing elevator installation 10.

- the power supply 101 is connected to the brake monitor 100 with at least one operating voltage VCC to provide.
- the relay circuit 103 of the brake monitor 100 is integrated in a safety circuit 20 of the elevator system or connected to a control voltage of the drive controller 12.
- the brake monitor 100 preferably has a reset switch which is actuated after the installation of the separate brake monitor 100 or after the fault of the elevator installation 10 has been rectified. By pressing the reset switch, the brake monitor 100 is transferred to a defined initial state. In this case, for example, the error memories or counters C1, C2, C3 are reset (initialized).
- the brake monitor 100 When installed, the brake monitor 100 may also be configured by making adjustments (e.g., setting parameters, setting switches, bridging or DIP switches, etc.). Brake monitor 100 may also be configured to be able to process a pulse signal (eg, the pulse signal of a pulse tacho to monitor engine speed).
